Largest U.S. Municipal Utility Deploys Advanced Smart Grid Network



March 28, 2013 By

This week, CPS Energy -- the largest municipal utility in the U.S. -- officially announced a new partnership to help deploy a smart grid network.

The San Antonio, Texas-based utility, which serves more than 740,000 electric and gas customers in the San Antonio metropolitan area, partnered with Silver Spring Networks to deploy features such as advanced metering and distribution automation. 

The smart grid network operates on Silver Spring’s open IPv6-based networking platform, which the company says enables utilities and infrastructure operators to deploy advanced smart grid features.

“Because we’re all using that standardized [IPv6] platform, we can work with other types of technologies to incorporate them as new technologies become available,” said Lisa Lewis, a spokeswoman for CPS Energy. “This is such a rapidly changing and growing field that as new things become available, as long as they’re formatted and fit this platform, we should be able to plug them in.”

CPS Energy would like to develop long-term strategies for making its smart grid more efficient, Lewis said. Thanks to the new partnership, the utility is now investing in plants and resources that have low- or no-air emissions to address concerns over air quality in the San Antonio area, as well as other infrastructure improvements to create efficiencies.

Lewis said CPS Energy will now be able to add a spectrum of new devices to the network, like smart meters, smart switches and other technologies that make the grid function more efficiently, thanks to Silver Spring's optimization of the electric grid in San Antonio combined with the company’s mesh network.

On the West Coast, the Sacramento, Calif., Municipal Utility District (SMUD) has partnered with Silver Spring since 2009 and has worked on a number of utility improvements with the company, said Don Jacobs, SMUD’s PMO manager and technology coordinator. 

SMUD plans to work with Silver Spring to go beyond traditional smart grid infrastructure -- a pilot program to extend the Silver Spring infrastructure to host vehicle charging stations is currently being rolled out. Approximately 60 electric vehicle customers will take part in the pilot, Jacobs said.

Good to see CPS moving forward. Fact check: Is CPS really the largest municipal utility in the US? LADWP serves over 1.4 million electric meters and 676K water meters, and a population of 3.9 million residents. Not sure this headline is accurate -- when I read it I just assumed this was LADWP.

CPS is the largest that provides both electricity and gas, but the article doesn't qualify it as such
